DRAIN AND RETuRNiNG STEAM TRAP.

SPECIFICATION forming part of Letters Patent No. 278,390, dated May 29, 1883.

Application inea April 6,1383'. (No model.)

l known as a drain-trap, by means of'which,

whenwater arrived at the end of the system, it was allowed to escape to the atmosphere, but when steam followed it was prevented from escaping, the other kind known as au l tomatic -retnrn steam traps, for which I have obtained numerous patents in the United States, by means of which the Water returning from alclosed system of coils is automatically returned to a boiler,under pressure, byopenin g an equalizing-valve connecting with the steam t in the boiler.

My improvement relates to a. combined return steam trap and drain trap, by means ol' which the same apparatus can be used at will to accomplish theresults hitherto accomplished by these two different contrivances.

Fig. 2.

My invention will be readily understood from the accompanying drawings,in which Figures 1 and 2 represent sections through my apparatus, Fig.1 being taken on a line a little farther back from the eye than the section shown in Fig. 3 represents a detailed view of the register-valve shown at Fig. 2.

The apparatus shown in these drawings was patented to me on the 5th day of December, 1882, No. 268,384, with the exception ot' the additional contrivances enabling the apparatus to he used at will as a drain-trap. I shall therefore only describe these additional contrivances, the apparatus being otherwise made as described in my previous patent.

In pipe E, which descends into the tank T, is placed a screw-stem, a. To the bottom of this stem the valve b is'attached. By turning the handle c the valve b can be opened and closed. Attached to the'tube h, forming part of the bucket P, is the lever d. This lever is slotted lat the end and connected by a pin to the tube 7L. To the other end of this leverdis attached the register-valvco. The detail ot' this is shown in Fig. 3. The register-valve is closed against its seat by a spring, s. The pipe G, which, in the ordinary operation ofthe contrivance, passes t-he return-water to the boiler, is continued, as shown at G', whichv pipe is provided with a valve, p. In the or` dinary operation of the apparatus the valve p is closed and the valve b is opened. The contrivance will then operate, as detailed in my previous patent, as an automatic return steam trap.` In practice this valve may be lower, if desired.

When it is intended that the apparatus shall operate as a drain-trap `the valve b is closed and the `valve 19 is opened. t In this condition of the apparatus, whenever the bucket P is floated the valve o is closed, and consequently no escape through the pipe G' to the seweris possible; `but whencver'the apparatus becomes `Iilled with Water and the bucket P sinks the valve o is opened and the water is forced upward through the pipe E, the pipe G, and the pipe G to the sewer.

The pipe G may connect, as described', with the sewer, or may connect with any suitable water-receptacle .ot' less pressure than the coils, thereby allowing the water to be forced into `said receptacle.

What I claim as my invention, and desire to secure by Letters Patent, is r 1. The combination of an automatic returntrap and an automatic drain-trap in one apparatus, whereby the apparatus may be used either for feeding the water of condensation into the boiler or discharging it into a suitable receptacle, substantially as described.

2. An automatic steam-trap provided with a valve connected to the delivery from the trap andV operated by the motion ot' the trap, and an independent pipe connected to said return-pipe from the steam-trap to the boiler` and delivering to the sewer or a water-receptacle, substantially as described.
